Description
Sanjeeb Pradhan and co-authors test whether fasting time predicts low blood pressure after spinal anaesthesia in a 2026 observational study. Long fasting before surgery is feared to drain body fluid, yet natural compensation may offset that loss. The team measured fasting length, an ultrasound index of vein fullness, and pressure drops in 51 adults having surgery below the navel.
The vein collapsibility index rose clearly with longer fasting. Fasting length alone separated later pressure drops poorly, while the ultrasound index did moderately well and stood as the only independent predictor in adjusted models. A one percent rise in the index raised the odds of a pressure drop slightly, which favours scanning over clock watching.
